If you are playing it safe with less than a week to go before the Iowa Caucuses, it may well mean that you know you have things in the bag.

Of course, it may also mean that you are about to be set up for a huge fall. And I’m not sure that crowds at Clinton campaign events will appreciate not having their questions taken. By all accounts, the race in Iowa is still a close run thing. Arrogance on the part of one candidate may make all of the difference between winning and losing.
